Filed: 1963-03-21
Abstract: 967,576. Cartons and blanks for same. AMERICAN CAN CO. March 21, 1963, No. 11224/63. Heading B8P. A cut, separating adjacent closure flaps of a tubular carton, stops short of the flap hinge line at a transverse cut extending into the flaps whereby a web is formed by planar tearing of the closure flaps when they are outfolded. As shown, cuts 40 which may extend only partly through the material terminate the separating slits 30, 31 between flaps 15 to 17. A blank (Fig. 1) is formed into a tube by folding flap 10 about score line 1 so as to overlie the flap 14 and securing; flap 15 being simultaneously secured to flap 26. After setting up, each end of the tube is then closed by firstly outfolding flaps 15, 16 and 17, causing planar cleavage of the material beginning at the junction of cut line 40 with the separation cut 42 and extending through the blank progressing outwardly along the cut 40. The webs 50 thus formed lie in a plane substantially perpendicular to the side walls. Flaps 18 and 19 are then folded over the open end of the tube, flap 19 being secured to flap 16 and the end closure is completed by infolding flaps 15, 27 and 17, 33 and finally flap 16, 19. Preferably the whole interior of the blank is coated with polyethylene. Each of the sealing points at the stage shown in Fig. 8 will then have a polyethylene to polyethylene contact except where flap 18 meets the webs 50. In a modification (Fig. 11) the cut line 40 does not extend wholly through the blank and is provided with downwardly extending end portions 40b to facilitate better directional control in forming the web 50.

Patent GB-788357-A (GB)
Title: A brewing process
IPC: C12C7/20
Filed: 1954-04-21
Abstract: In using ultrasonic or audible sonic energy for the extraction of hops for brewing, the hops are extracted in cold liquid, such as water or wort, at a temperature not exceeding 95 DEG  F., the extract so obtained is separated off and the residual hop husks are further extracted in hot liquid at a temperature higher than 150 DEG  F. Ultrasonic energy may be used for the cold extraction and audible sonic energy for the hot extraction.  According to an example, a suspension of 50 1/2 lb. of hop in distilled water, in an atmosphere of carbon dioxide, is subjected to ultrasonic energy for 3-4 hours at 55-65 DEG  F., the extract is separated, the husks are mixed with distilled water and subjected with free access of air to ultrasonic energy for 2-2 1/2 hrs., initially at 212 DEG  F. and later at a pressure of 1.3-1.4 atmos. and temperature of 250 DEG  F.  The spent hop is added directly to beer wort in the brew kettle, the liquor from the hot extraction is added one hour after the commencement of boiling of the wort, and the liquor from the cold extraction is added to the hot-beer tank when the wort temperature had decreased to 160 DEG  F.; alternatively the cold extract may, after pasteurization, be added to the wort during fermentation or to green beer in a lagering tank.

Abstract: 387,180. Sliding-clasp fastenings. PRENTICE MFG. CO., G. E., New Britain, Connecticut, U.S.A.-(Assignees of Prentice, G. E. ; New Britain, Connecticut, U.S.A.) April 22, 1932, No. 11604. Convention date, Jan. 6. [Class 44.] In sliding-clasp fastenings having flexible stringers 1, 2 carrying fastener elements 6, 7, a slider 5 having a divider neck 10 and convergent channels 14, 15, and end stops 16 for limiting movement of the slider in the gapclosing direction and adapted to be concealed in the channels in the closed position, each end stop is so shaped that in the closed position a portion of the lateral edge of the stop engages the side wall of the slider channel so as to oppose backward movement of the slider. The side walls of the channels 14, 15 are shaped to provide upper and lower cam surfaces 11, 12, the slider being thus waisted at a point 13. The end stops are formed from metal blanks folded to provide legs for gripping the stringers and present upper and lower cam portions 25, 26 diverging from a point 23. As the slider is pulled to close the gap, the end stops become wedged therein and lock it in position. After the point 13 passes the edge of the lower cam portion 26 the slider slips into position with a click. A final seating of the slider and end stops is effected with the lower ends of the stops projecting below the lower end of the slider. In order to facilitate the locking movement, the angle between the surfaces 25, 26 is less than that between the portions 11, 12. The lateral pressure between the end stops may be eased by forming them with complementary recesses 31.
